FINDER' FOR CAMERAS.

Specification of Letters Patent.

Patented March 23, 15509.

To all whom it may concern:

Be it known that I, WILLIAM E. SHANLEY,4

a citizen of the United States, residing at Norwich, in the county of New London and' State of Connecticut, have invented certain new ,and useful'j" Improvements in Finders for Cameras, of which the following is a specification.v The immediate object of this invention' is to provide a convenient, effective andreasonablycheap form of finder forcameras, and particularly for that class of hand cameras which are intended to be used either in an upright or horizontal position, and the principal feature of novelty in my said invention consists in means for automatically moving the field .of the finder into parallel relation to the plate or lm; that is to say, when the camera and plate are held upright the field ofthe finder is 'seen in an upright position and when the camera and plate are iorizontal the field ofLthe finder'is correspondingly adjusted.

' In order to explain my said invention clearly I have provided the annexed drawings, in which,-

Figures 1, i2 and 3 are, respectively, side, plan and front views of a camera of the well known Lkodak type having attached thereto a finder embodying my present improvements Figs. 4 and 5 are relatively enlarged, detached, perspective, views of said finder, Fig. 4 showing vthe same adjusted to take an upright picture and Fig. 5 being adjusted to take a horizontal picture. Figs. 6, 7, 8 and 9 are still further enlargements of said finder representing the same as follows :Fig. 6 is a side elevation and Fig. 7 is a central, vertical, sectional view of said finder. j Fig. 8 shows, partly in section,- those parts located -below the line 8 of Fig. 6, an'd'Fig. 9 is a front elevation, partly in section, showin those parts in the rear of line 9- of said Fig. 6.

Referring to these drawings, the letter a indicates a'camera, b the adjustable front of said canieravto which is secured, by means of an anglelate c', my improved finder.

The casing ot said finder, as here illustrated-- is generally. of triangular outline, when viewed fromA one` side, the lens d beinv" mounted a suitable tube in the 'vertical frontV wall and the mirra: 1r reflector e being mounted upon the in] ierface of the rear wall of said casing; said rear wall being hinged at e so that it may be opened, as seen in dotted lines in Fig. 6, in order that said reflector' may be cleaned and polished. The said rear wall is retained in its closed position by a i spring latch f o'r l by some other suitable means. j

Mounted to revolve in the top plate of the described casing is a disk g that is provided A, with an lopening g which serves to outline the field of View, and said opening is sha ed and proportioned to correspond to the p ate or film to be exposed. A portion of the edge of disk g is provided, as here shovtn, v, ith gear teeth g2 and these teeth are engaged by similar teeth h on a disk h that is mounted to partially rotate inthe front .iallv of the finder casing. I have thus far found it convenient and practicable to mount disk h on the lens tube `but the particular manner of supporting said disk is not. material.

The angle plate c, uhich I have already mentioned as the finder support, is an integr'al part of disk h and extends tangentially from the perimeter of said disk and the disk 'is so formed that shoulders hL-h3 are provided that are adapted to engage stop pins c-c to limit the rotary adjustment of disk h in either direction. The sup orting plate c always preserves a fixed and dpefinite relation 4to the camera front, the inder'casing being -partially rotated in oron said support u hen the camera is changed from an iorizontal to a vertical position, or vice versa, as the case may be.v In Figs. 1 and v5 the finder is adjusted to make an horizontal exposure l,while in Figs. 2, 3 and 4 the finder is adjusted to make-an upright exposure. It will thus tially rotating thefinderso t at it may serve its purpose both in an horizontal and vertical position results, in my described, improved, finder in automatically adjusting the field of vievv to correspond' to the outline of' the desired negative and this I accomplish by very simple and inexpensive means.

be seen that the ordinary operation of par? Having thus described my invention, I to conform to the outline of the desired '-)lam as new and Wish to secure by Letters negative, as the finder is partially rotated.
